Awl --
Apropos of the recent thread on wire nutting stranded with solid, are there
any inherent advantages of one over the other? #14-#10.
Stranded is more flexible, an advantage if you have to pull long runs in
bends in EMT, but I find it a pain when connecting outlets, etc.
Stranded can be dicey-er with nicks, missing strands.
But, stranded might give more contact area under screws, in breakers, etc.
At HD, stranded is $5 more on 500 ft coil of 14 and 12: $25 to $30, and $40
to $45.
BX/romex comes which way? Both?
Who uses what and when?

Yes and yes.

Only missing strands if one cuts them off.

Not an issue.

You seem to have pretty well covered all the properties and pros and
cons of solid vs. stranded.

Solid only. No need to snake the wires through anything, so no need for
stranded wire here.

You pretty well said it yourself:
o Use stranded wire when pulling through conduit.
o Use solid wire otherwise.

Actually CMPCT-CU conductors in aluminum flex (BX ) cable IS
available. CMPCT-CU is otherwize known as compact copper, or stranded
wire. as per ASTM b-8

The stranded stuff is used where flexability is required - or where
vibration is a problem. You won't find it at the "borg" but I do have
some in my garage.

Stranded wire "BX" is available from "Northern Cable" in TC90, MC-THHN
and AC-THH flavours. Google it.

The contact area of solid wire under the screw will be several times
the cross-sectional area of the wire. Nothing to be gained from more
contact area than that. Stranded also has a tendency to squeeze out
from under the screw and loosen up.
Other than that, I think you covered most of it.
